- Abstract
In the study of the aerodynamic load applied by the air on the rotating helicopter blade, it is important to know that the values obtained from the numerical analysis are as close to reality as possible, within an acceptable limit. Therefore, in order to realize and obtain a pertinent result from a structural analysis, based on pressure loads obtained from the airflow surrounding the blade, it is important that the fluid flow results are certified by comparison with experimental result. In order to achieve this purpose, the tail rotor blade of the Romanian Air Force IAR330 helicopter has been modeled using Ansys Workbench and by using Fluid Flow, the values of the pressures on the main blade surfaces have been determined. The experimental values of the aerodynamic pressure have been determined using a 1:1 scale model of the blade, placed in the subsonic aerodynamic wind tunnel at INCAS Bucharest.
